Functions Reference
(pf.)flanger_mono
Mono flanging effect.
Usage:
_ : flanger_mono(dmax,curdel,depth,fb,invert) : _
Where:
- dmax: maximum delay-line length (power of 2) - 10 ms typical
- curdel: current dynamic delay (not to exceed dmax)
- depth: effect strength between 0 and 1 (1 typical)
- fb: feedback gain between 0 and 1 (0 typical)
- invert: 0 for normal, 1 to invert sign of flanging sum
Reference
(pf.)flanger_stereo
Stereo flanging effect.
flanger_stereo is a standard Faust function.
Usage:
_,_ : flanger_stereo(dmax,curdel1,curdel2,depth,fb,invert) : _,_
Where:
- dmax: maximum delay-line length (power of 2) - 10 ms typical
- curdel1: current dynamic delay for the left channel (not to exceed dmax)
- curdel2: current dynamic delay for the right channel (not to exceed dmax)
- depth: effect strength between 0 and 1 (1 typical)
- fb: feedback gain between 0 and 1 (0 typical)
- invert: 0 for normal, 1 to invert sign of flanging sum
Reference
(pf.)phaser2_mono
Mono phasing effect.
Phaser
_ : phaser2_mono(Notches,phase,width,frqmin,fratio,frqmax,speed,depth,fb,invert) : _
Where:
- Notches: number of spectral notches (MACRO ARGUMENT - not a signal)
- phase: phase of the oscillator (0-1)
- width: approximate width of spectral notches in Hz
- frqmin: approximate minimum frequency of first spectral notch in Hz
- fratio: ratio of adjacent notch frequencies
- frqmax: approximate maximum frequency of first spectral notch in Hz
- speed: LFO frequency in Hz (rate of periodic notch sweep cycles)
- depth: effect strength between 0 and 1 (1 typical) (aka "intensity") when depth=2, "vibrato mode" is obtained (pure allpass chain)
- fb: feedback gain between -1 and 1 (0 typical)
- invert: 0 for normal, 1 to invert sign of flanging sum
